H EAD-CHAI R FOR STU B-SWITCH ES FOR RAI LWAYS.

SPECIFICATION forming part of Letters Patent No. 463,430, dated November17, 1891. Application filed May 4, 1891. Serial No. 391,515.' (NomodeL)To all whom it may concern:

Be it known that I, ROBERT C. SoHENcK, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Head-Chairs for Stub-Switches for Railways, of which the following is a full, clear, andexact description, reference beinghad to the accompanying drawings,forming part of this specification.

The invention relates to head-chairs or switch-chairs forrailway-switches in which an iron chair is provided fastened to the tieto receive and support the ends of the rails, so that they may bebrought into proper alignment and firmly supported and held in place,the details of which will be more fully hereinafterset forth anddescribed.

In the accompanying drawings, Figure l is a perspective view of a triplestub-head chair embodying my improvements. Fig. 2 is a perspective viewof a double-head chair embodying my improvements in a slightly-modifiedform.

These head-chairs have been made of ordinary cast or gray iron; but inorder to fully resist the weight and jar must be made so heavy as to beexpensive and inconvenient to handle. To overcome this difficulty theyhave also been constructed of wrought-iron; but.

when so made they are in parts or sections riveted together, and the jarsoon shakes them to pieces or deranges the parts and loosens the jointsand they are forced out of shape. Attempts have also been made to makethem of. malleable iron; but when made thick and heavy enough it wasimpossible to thoroughly anneal them throughout. In order toeffectthisthorough annealingandalso tolighten them, they were thenpaneled out on the under side; but practice has shown this to beundesirable, as the ribs cut into the tie renderof the fixed rails bythe rib c.

chair is constructed with the flat surfaces 01 d to receive the ends ofthe stationary or fixed rails, which are anchored in place by theflanges a a on the other side of the chair, the broad-flat surface 19receives the end of the movable switch-raiLseparated from the ends Thebase of the chair is provided with openings e e for spiking it securelyto the tie.

In casting the chair, cores are used extending through or partly throughbetween the upper and lower faces and producing the openings f f, whichpreferably extend almost entirely through the chair, or may extendentirely through, it being a little more convenient in casting to extendthem not quite through. Theseppenings f f leave the solid.

metal ribs g gbetween them, which form substantially a series of I-beamsbetween the upper and lower portions of the head-chair. When thusconstructed the entire mass or body of metal can be throroughly annealedthroughout, whichis donein the usualmanner. The form is much strongerand better adapted to resist the strain as-applied, and a headchair isproduced in a single piece stronger than any other form of casting andbetter' than wrought-iron, as it cannot Work to pieces. Much less metalmay be .used than in a grayiron chair and it is many times as strong.

Having thus described my invention, what I claim, and desire to secureby Letters-Patent, 1s

1. As an article of manufacture, a metallic head-chair made of one piecethroughout and having the base-plate cored, whereby the whole may bethoroughly annealed, substantially as shown and described.

2. As an article of manufacture, a metallic head-chair made of one piecethroughout, cored out between its upper and lower faces in the mannerdescribed, so that the upper portion is supported on a series of ribsinte gral with the body of the chair, and the lower face forms a broadsupport adapted not to cut into the tie, and so that the whole may bethoroughly annealed, substantially as shown and described.
